//单选按钮对话框

builder.setNegativeButton(“取消”, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, “您选择了取消！”, Toast.LENGTH_SHORT).show();
}
});
//创建单选对话框里的数据源
final String[] days = new String[]{“星期一”,“星期二”,“星期三”,“星期四”,“星期五”,“星期六”,“星期日”};
builder.setSingleChoiceItems(days, 1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, “您选择了：”+days[which], Toast.LENGTH_SHORT).show();
}

//创建并展示

builder.create().show();

}

//自定义对话框
AlertDialog alertDialog;
private void zidingyi() {
//inflate是自己自定义的一个布局
View inflate = View.inflate(MainActivity.this, R.layout.layout, null);
